Just over two weeks is all that remains before the citizens of the United Kingdom cast their votes as to whether the nation in which they reside should remain a member state of the European Union, or whether it should go it alone as an independent sovereign nation.
No referendum was held when Britain agreed to an accession treaty on 22 January 1972 together with the EEC (European Economic Community) states, Denmark, and Ireland, or when the European Communities Act 1972 went through the legislative process. Britain joined the European Economic Community on 1 January 1973, along with Denmark and Ireland.
Throughout the 1980s and 1990s, discussions had been held on allowing a referendum to take place, however here we are 44 years after Britain joined what was then the EEC, with votes about to be cast.
Today’s economic and commercial landscape is considerably different to that of 44 years ago. Britain is a financial powerhouse, home to the largest interbank FX trading center in the world by a considerable margin – just 6 banks, all located in Canary Wharf in East London, account for over 46% of all global interbank FX order flow, and the City of London is an ultra-modern, highly technologically advanced financial powerhouse, hosting the majority of the institutional FX companies and prime of prime brokerages which power the non-bank electronic trading industry for the entire world.
Britain’s pound is the most highly valued currency in the world by a considerable margin, and has been for many years.
Such an important mainstay of the European economy, Britain is a shining light of ingenuity and financial prowess, therefore, the potential outcome of the referendum on what has been dubbed ‘Brexit’ from the European Union is a matter for all brokerages and traders to concentrate on.
Indeed, a potential exit from the European Union could be the cause of high volatility in the FX market, as such an important country goes it alone, just as remaining in the European Union may lead to volatility as the European sovereign debt would still present a burden to the British Chancellor of the Exchequer’s balance sheet.
In 2015, the Swiss National Bank removed the 1.20 peg on the EURCHF pair, sending the currency markets into a sudden period of unprecedented volatilty, exposing brokerages to negative client balances and in some cases causing their insolvency.
The British pound has never been pegged to the Euro, however a similarly volatile situation could occur in the days following the result of the referendum.
FXPRIMUS maintains responsibility to clients, increases margin on Sterling pairs by 2%
FXPRIMUS Head of Dealing Ioannis Gerousis today explained to FinanceFeeds: “Business will continue as usual for trading on the Sterling pairs, except that the company has decided to increase the required margin on Sterling pairs to a minimum of 2%, in order to help manage risk during this particularly volatile period. We are monitoring the polls on continuous basis, and our experts remain vigilant to pickup any development that might occur. ”
Indeed, it is clear that the increase in margin requirements by brokerages wishing to safeguard themselves and their clients against any extreme volatility is a common direction against those with prudent risk management controls in place.
